Hi,

You can refer to Stacey's discussion here http://www.manhattangmat.com/forums/og- ... t1277.html
I found it to be a nice explanation of this problem.

-ed form modifies the closest noun. So 'called' must modify 'technique'. C, D and E are out.

'Originally developed for detecting air pollutants' and 'having the ability to analyze the chemical elements' are two modifies of 'a technique'. Either both should be closer to 'technique' or must be connected with a proper conjunction. It is lacking in option B.

A is the best, considering modifier placement, and verb agreement.

C) the modifier "called proton-induced X-ray emission" should be placed closer to "A technique"

Hi noboru,
"Which" is not modifying emission, it is modifying "proton-induced x-ray emission". That's the noun.
"Which" gives more detail abou the technique. That's why A is correct.

Hope it helps

Actually I think that "which" modifies "technique", which would make sense to me. In that case, "called proton-induced x-ray emission" is kind of an adjective that gives more detail to "technique".
What do you think about that?

Why is E not the answer

Because "Called proton induced x-ray emission" is not place after technique.

A is the answer.As the introductory phrase refers to proton-induced x-ray emission and technique correctly modifies it.

C is wordy and awkward construction. In Gmat sentences which are concise and clear are preferred.

A for me too...
C and D distort the meaning by saying that the technique was originally developed....
B has issues with modifiers... The first dependent clause does not hav any connection with the rest of the clause...
E is incorrect because it has 'run-on' sentences.. Moreover it is wordy...

WHICH in A and C both refer to emission. But as per OG A is correct and C is incorrect.

Can anyone elaborate on this one?

To keep it simple, here's how we look at it:

Originally developed for [X], [a particular technique]...is finding uses in x, y, and z.

This is a lot easier to comprehend and work with. Thinking like this will cut down the potential for stupid, overlooked mistakes.

Pay attention to "prepositional phrases" - keywords like "for" "in" etc...or just general phrases.

In the above example, I read:

"which can quickly analyze the chemical elements"

as "which can blah blah blah"

I read: "in almost any substance without destroying"
as: "in blah...without destroying it"

I read: "Originally developed for detecting air pollutants"
as
"Originally developed for blah..."

I read: "a technique called proton-induced X-ray remission"
as
"a technique called blah.."

Get used to using "blah" to replace fancy parts of the sentence and you'll be surprised at how simple a lot of these GMAT questions actually are.

What do you think about that?

I agree that "which" modifies technique. I just started studying SC seriously so this may not be 100% correct, but I would agree with noboru's second point that "called proton-induced x-ray emission" is an adjectival phrase.
